Airworthiness Directive · Amendment 39-10917 · Stemme GmbH & Co. KG Models S10, S10-V, and S10-VT Sailplanes
Stemme GmbH & Co. KG Models S10, S10-V, and S10-VT Sailplanes
The following models and serial number sailplanes, certificated in any category: Model Serial numbers S10........................... 10-03 through 10-63. S10-V......................... 14-002 through 14-030 and transformed S10-V sailplanes with serial numbers of 14-012M through 14-063M. S10-VT........................ 11-001, 11-004 through 11-013, and 11- 015.
This amendment adopts a new airworthiness directive (AD) that applies to certain Stemme GmbH & Co. KG (Stemme) Models S10, S10-V, and S10-VT sailplanes. This AD requires inspecting certain areas in the flight control system for cracks; immediately replacing any cracked parts; and eventually replacing all longitudinal coupling with modified coupling regardless if found cracked. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to detect and correct cracks in certain areas of the flight control system, which could result in flight control system failure with consequent reduced or loss of control of the sailplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
